3 Claims.

This invention relates to door latches and particularly to a door latchembodying a member with a recessed portion having a transverse abutmentand a cooperating member provided with a projecting portion whichabutment and portion are adapted for resilient engagement with eachother for holding the door in its closed position. One of the principalobjects of the invention is to provide a latch of this type which willnot become clogged by paint or varnish in its working parts and anotherobject is to provide an article in which the outer finish of the exposedpart is not produced by painting, varnishing or the usual forms ofenamel. Still another object is to pro-- vide a device of this typehaving improved and novel means for assembling or applying the parts andalining the same. And a further object is the production of an improvedlatch of the above type which is more simple and of lower cost of 0manufacture than those now lnuown to us.

With the foregoing and other advantageous features in View which willappear as the description progresses, we have illustrated ourimprovements in the drawings accompanying and forming part of thisspecification, and in which- Figure 1 is a front elevation showing oneform of our invention applied to a door.

Fig. 2 is a vertical section of the same taken on the line 2-2 of Fig.l.

Fig. 11 is a front elevation of the stationary portion of this form.

Fig. 12 is a front elevation of another form of our improvements.

Fig. 13 is a vertical section of a part of the same taken on the line13-13 of Fig. 12.

Fig. 14 is a vertical section of the same taken on the line 14-14 ofFig. 12.

Like characters of reference refer to like parts in the several figuresof the drawings.

Referring first to Figs. 1 to 6 of the drawings, the numeral 2 indicatesa member which is secured to the movable portion such as the door Dwhich is to be latched. This form of the member is formed with a raisedmiddle portion 3, side 0 portions 4 through which suitable screws 5 arepassed to secure it to the door D, and beveled portions 6 along theedges of the side portions.

If desired a knob 7 may be provided for opening and closing the door orother article to which 5 the device may be applied, said knob being heldby a screw 8 passed through the knob and a suitable aperture in themember 2 into the door D. The raised middle portion 3 is grooved at 9 onthe inner side of said member and has two oppositely disposed abutments10 formed by the inner surfaces of the side walls of said groove 9. Thesaid abutment-,5 are preferably provided with indented or beveled partsor notches 10 for the engagement of parts presently to be described.

The member 2 may be formed in any suitable manner but is preferably madeof sheet metal in the form of a stamping l1 and a covering element 12 ofsuitable material such as glazed celluloid of any desired color issecured to the 80 stamping 11. This may be eifected in any suitable wayas by turning under the edge portions 13 as shown in Figs. 3 and 4.

' There is a member 14 provided to be engaged by the member 2 to holdthe door or other article fitted with it in its closed position as inthe doorway of the doorway frame F and said member 14 is provided with aportion 15 transverse to the door front surface to engage the transverseabutment in the member 2. In the form 9 shown in the figures two suchportions 15 are provided and each may be furnished with a rounded orcurled part 16 so that the abutments 10 may readily pass on and off themand to engage in and hold by the notches 10 when these 9 are provided.There is also a base portion 18 joining said portions 15 said portionbeing provided with a perforation 19 through which is passed the screw20 for securing the member 14 to the frame F of the doorway. There is analining element 17 preferably placed at the upper end of the member 14and formed by bending over a portion of the same transverse to the baseportion 18. The door is fastened by the foregoing device by merelypushing it firmly to its place in the doorway and the curled parts 16then immediately engage with the indented parts or notches 10' and holdthe door in place and it is opened by firmly pulling it outward.

When it is desired to apply this form of latch to a door or otherarticle, the member 14 is first placed in position on the frame of thedoorway as shown in Figs. 5 and 6 with the portion 17 alined on the edgeof the frame F. The screw 20 is then applied and the member secured inplace. Next the door D is closed and the member 2 is placed on the frontof it, placing the recess or groove 9 over the portions 15 and aliningthe raised middle part 3 to the edges of the door D. The screws 5 arethen applied and the handle or knob '7 if there be one is secured inposition.

In the form of our invention shown in Figs. '7 to 11 inclusive, themember 2 is in the form of a heart-shaped metal plate or stamping 21 andhas a cover element 22 similar in form but preferably furnished with araised part 23 having a recess 24 in its inner surface and immediatelyover a pair of perforations 25 in the plate 21. At the adjacent edges ofthe perforations are placed the abutments 9, which are here formed bythe struck up flanges 26 on said plate 21.

There is a member 1a to be engaged by the abutments 10" and said memberis similar to the member 14 of Figs. 2, 3, 5 and 6. Said member 14 hastwo transverse portions 15 and 2'7, the former provided with a roundedor curled part 16' and the latter being without such part. These twoportions resiliently engage the abutment surfaces 10 on the outer sidesof the struck-up flanges 26. The member 14' is secured on the doorwayframe F or other suitable member and instead of the arrangement shown inFigs. 1 and 3, the inner portions of 15 and 27 engage the outer surfaces10 and the curled part 17 engages the top of the right hand flange 26. Asuitable screw 20' passed through the aperture 19 secures the member 14to the frame F. The method of fastening and unfastening the door issimilar to that for the first form of the invention.

In the form of our invention shown in Figs. 12, 13 and 14. there is aheart-shaped plate or stamping 30 held by the screws 31 on the door D2and also a knob 32 held by a screw 33.

- Fastened to the plate 30 is an element 34 having portions 35 and 36transverse to the door surface and preferably resilient and joinedtoeach other by the top portion 3'7. The portion 35 is preferably moreresilient than the portion 34 and has a struck-in portion 38 preferablycircular in form. There is a ring 39 preferably of round wire andprovided with a screw threaded stem 40 by which it is fastened to thedoorway frame F2. When the door D2 is closed the portions 35 and 36resiliently clasp the ring 39 as seen in Fig. 14. On giving the knob 32a strong pull the door is opened and it is shut by pushing it firmly toplace in the doorway.

What we claim is:-

1. In combination, a member secured to a door having a portionoverhanging the frame of the doorway and provided with a pair ofoppositely disposed, relatively fixed, spaced abutments, and a devicesecured to said doorway frame and alined to said member, provided withtwo relatively movable elements each having a free end portion adaptedto engage one of said abutments for holding the door closed.

2. In combination, in a door latch, a member secured to a door having aportion overhanging the frame of the doorway and provided with a pair ofoppositely disposed, relatively fixed, spaced notches, and a devicesecured to said doorway frame which includes a flat portion by which itis secured to said frame and two outwardly extending elements one ateach end of said flat portion and whose free end portions are movablerelatively to each other and adapted to engage said notches for holdingthe door closed.

3. In combination, a door member embodying an outwardly covered recesshaving two opposed notches, and a door jamb device including a stampedmetal member and a single holding screw therefor having a head, saidstamped metal member provided with a flat base having a perforation forsaid screw, a rearwardly turned alining element and two forwardly turnedresilient holding elements each of the latter having a free end toengage in one of said notches when the door is closed, said holdingelements spaced apart a distance not less than the diameter of saidscrew said perforation being between said elements and said notches inworking alinement with said holding elements, and said alining elementbeing in alining engagement with the edge of the door jamb.
